Eagle Libraries

I often need slightly customised headers or connectors for various purposes. In this instance I needed a surface mount 0.1" header footprint which I later replaced with the modified 8 pin through hole header. Lastly I needed a footprint for a terminal block that has 2 solder contacts but is only a single output. Interesting parts all in all.

A supplier example is here: Farnell

Eagle library (for 8 pin version) here: SMD Header

This is the footprint of the modified 2X4 0.1" header. This is to allow 4 inputs with a VCC and GND that is no wider than the 4 data pins themselves. I doubt this is a readily available product...

Eagle library: 2X4 Header Modded

Finally I want to be able to use screwless terminals in my projects. An example of a product that would fit into the footprint: Farnell

The footprint looks like this in Eagle:

Eagle library: Edge Wire Terminal

Thanks for looking.

This is a high speed counter that is able to circumvent the ripple effect in other more conventional counters (often known as ripple counters). This counter has a maximum input frequency of 230MHz and a propagation time of <4ns on all outputs. This is going to be the counter IC in a frequency counter project that I am currently working on.

Sadly there aren't any particularly interesting pictures of this IC so here is a link to the datasheet:

SN74LV161 Counter IC

and here is a current dropbox link:

Please message me if the links do not work and I shall endeavor to get them back up quickly.

This is a place holder for the LM2596 Buck converter bought on eBay. Basically just an easy way to prototype in Eagle.

The set pin is the 'centre' tap of the pot and it means that I can control the voltage output of the module with an input voltage.

Datasheet is here:

LM2596

My eagle library is here:

The LT3080 is a low dropout linear regulator. I will be using the big brother (the LT3081) in an upcoming project (Stay tuned for the LT3081 Eagle file and the project as well :D). I like this regulator as it is capable of true 0V output and has good noise performance.

Datasheet is here:

and my library for it is here:

As always, Let me know if there is anything you good people want to see.

This is a 4 channel 12-bit digital to analogue chip. It has buffered outputs, non-volatile memory and latches to synchronise the output voltages. I am intending to use this on my PSU project and my electronic load project. It has an I2C interface making it ideal for fast interfacing with minimal pins required.

The Eagle library is available from the Farnell website as a script but is also here:

The MCP4725 is the single channel version.

This is the Eagle library for the TS1100 current sense amplifier.

Power supplies are easy to buy in certain voltages like 36V or 48V DC. Its a simple case of finding an old server PSU which is rated at 54V and 2500W.

(CISCO WS-CAC-3000W 6500) is a good example £48 for 55A at 42V

Trouble is 42V is a bit high for most applications. The power is useful though so I started to make a high power (~1500W) DC-DC converter to power my brushless motors spindle (Oh so many outstanding projects)

Anyway. Here is the library:
